چکیده انگلیسی


• GCE was modified with polypyrrole/single-walled carbon nanotubes.
• The proposed modified electrode was used to detect quinoline yellow.
• It has lower limit and more sensitive signal for the detection of quinoline yellow.
• The method is very useful for determination of quinoline yellow in actual samples.

A novel modified electrode based on polypyrrole (ppy) and single-walled carbon nanotubes (swcnts) was developed for the detection of quinoline yellow. It is prepared via a simple and convenient method. Cyclic voltammetry (CV) and square wave voltammetry (SWV) were used to confirm the successful stepwise assembly procedure of the sensor. Under the optimal conditions, the fabricated electrode exhibits excellent electrochemical activity toward the oxidation of quinoline yellow. The liner range is from 0.8 to 100 μM, and the detection limit is down to 0.08 μM. The modified electrode also showed good accuracy, stability and reproducibility, which might be attributed to particular properties of polypyrrole, single-walled carbon nanotubes and synergic interaction between them.
